Oh, for gosh sakes, I thought as an "Old Timer", I'd seen or heard of
everything!
I've never seen that bearing froze up!
Thanks for reporting back.

Thanks for the replies, I took the scanner unit apart and found the
problem
to be the waveguide coupling bearing was siezed up. Because the waveguide
is
rectangular in shape and oriented with the long dimension fore and aft
produced the target display problem of not seeing targets port and stbd!

thanks again.

I have a small Furuno radar where the echo return image is missing on the
left and right portion of the screen. The fore and aft images are fine.

I suspect the "brushes" or slip rings in the scanner unit are worn in
the
2 o clock thru 4 o clock and the 8 o clock thru 10 o clock regions.
Am i correct in this assumption and if so, are kits available to renew
the
contacts in the scanner?

Thanks,
